snprintf()

The snprintf() function formats the given content and assigns it to the specified string. Only the specified number of bytes will be assigned to the destination string. Here is its syntax:

int snprintf(char *str, size_t numb, const char *format, ...);

Here's a breakdown of what the preceding code represents:

• *str: Represents the pointer that points to the string where formatted content will be assigned.
• numb: Represents the maximum number of bytes that can be assigned to the string.
• format: Like the printf statement, several formatting tags such as %d and %s can be used to format the content.

Note: snprintf automatically appends a null character to the formatted string.
